In the design of PCB Board and cooling system design includes cooling and cooling component choices, as well as considerations of cold expansion coefficient. Now PCB Board cooling methods commonly used are: through the PCB boards of cooling, the PCB Board with heatsink and thermal panels.

The component selection and layout design of 2.PCB Board

When the PCB Board design, no doubt to face the choice of components. Specifications for each component are not the same, even though the same product components of different manufacturers also may not be the same, so in the PCB Board design, choice of components, you must contact the vendor to know the characteristics of components and understand the effects of these properties on the PCB Board design.

3.PCB design for Testability design

PCB Board to test the key technologies include: testability, Testability Measurement, mechanism design and optimization of processing and fault diagnosis and test information. Testability design of PCB Board is in fact one can easily test test method of PCB Board, providing access to testing information channel inside the object to be measured.

4.PCB humidity level in the design of MSL

MSL:Moisure Sensitive Level, that is moisture sensitive level, stated on the outer label in moisture-proof packaging bags, divided into: 1, 2, 2A, 3, 4, 5, 5A, 68. Humidity has special requirements or humidity sensor mark on the packaging components must be effective management, to provide the material storage and manufacturing environments of temperature and humidity control, temperature and humidity sensitive components to ensure reliability of performance.
